Angular acceleration in 3D

Consider the rotor of a gyroscope. The rotor is attached to a frame that is rotating about a fixed vertical axes with a constant rate of ω 1, and with the rotor rotating relative to that frame at a ...

Zero velocity vs. zero acceleration

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Simulation and kinematic analysis of a 3-DOF marine antenna pedestal focusing on singularity avoidance and its effects on angular velocity and angular acceleration

The antenna pedestal is one of the main components of satellite communications on ships. This pedestal is a 3-DOF (3-degree-of-freedom) robot whose main function is to track the direction of the space ...
